  • Use of Iron Ore Pellets in Blast Furnace Burden – IspatGuru

    2014-06-13  Iron ore pellets are now the single largest source of iron for North American blast furnaces. Pellets constitute about 70 % of the blast furnace burden. Initially acid pellets (DRI grades) were produced and used in blast furnaces. In the mid 1980s, a number of pelletizing and blast furnace trials were conducted to evaluate the benefits of ...

  • Pellet Degradation Effect on Blast Furnace Performance

    A full survey of the laboratory and blast-furnace tests on 2 types of acid pellets is given. From the laboratory tests out in an atmosphere containing hydrogen, it appears that type B, produced out of 100% magnetitic ores, has a far better low temperature disintegration index and a lower reductibility index than type A, produced from a hematite/magnetite mixture.

  • Direct reduced iron - Wikipedia

    Direct-reduced iron has about the same iron content as pig iron, typically 90–94% total iron (depending on the quality of the raw ore) so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.

  • Pelletizing - Wikipedia

    Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...
